Julie Roberts created the ‘Sickert’s Shadow Portfolio’ in 2006, featuring a suite of five etchings within a self-contained box. This ‘colophon’, or introductory page, gives a brief description of the box’s contents. In the portfolio Roberts explores the theory raised by several writers, that Walter Sickert (1860–1942), one of Britain’s most outstanding artists, could have been the mass murderer known as Jack the Ripper. Sickert was drawn to the darker side of Victorian life, which was reflected in many of his paintings. He said in 1934, ‘It is said that we are a great literary nation but we really don’t care about literature, we like films and we like a good murder.’
